, 2010 In this era of significant advances in telecommunications and GPS sensors technology, a person can be tracked down to proximity of less than 5 meters. This remarkable progress enabled the offering of services that depend on user location (the so-called location-based services—LBSs), as well as the existence of applications that analyze movement data ...

A Trajectory Privacy Protection Method Based on Random Sampling Differential Privacy [PDF]
ISPRS International Journal of Geo-Information, 2021 With the popularity of location-aware devices (e.g., smart phones), a large number of trajectory data were collected. The trajectory dataset can be used in many fields including traffic monitoring, market analysis, city management, etc.

Personalized semantic trajectory privacy preservation through trajectory reconstruction
World Wide Web, 2017 Trajectory data gathered by mobile positioning techniques and location-aware devices contain plenty of sensitive spatial-temporal and semantic information, and can support many applications through data analysing and mining. However, attribute-linkage and re-identification attacks on such data may cause privacy leakage, and lead to unexpected serious ...

SCTP: Achieving Semantic Correlation Trajectory Privacy-Preserving With Differential Privacy [PDF]
IEEE Transactions on Vehicular TechnologyWith the rapid proliferation of vehicular technology, location-based services (LBS) have become a crucial component of Internet of Vehicles (IoV) applications, such as map navigation and health tracking. These applications rely on users' location information to provide services, enabling users to effectively share their locations, access information ...

Privacy Preservation in the Publication of Trajectories [PDF]
The Ninth International Conference on Mobile Data Management (mdm 2008), 2008 We study the problem of protecting privacy in the publication of location sequences. Consider a database of trajectories, corresponding to movements of people, captured by their transactions when they use credit or RFID debit cards. We show that, if such trajectories are published exactly (by only hiding the identities of persons that followed them ...

A Privacy Risk Model for Trajectory Data [PDF]
, 2014 Time sequence data relating to users, such as medical histories and mobility data, are good candidates for data mining, but often contain highly sensitive information. Different methods in privacypreserving data publishing are utilised to release such private data so that individual records in the released data cannot be re-linked to specific users ...

Privacy through uncertainty in location-based services [PDF]
, 2013 Location-Based Services (LBS) are becoming more prevalent. While there are many benefits, there are also real privacy risks. People are unwilling to give up the benefits - but can we reduce privacy risks without giving up on LBS entirely?

Maintaining trajectory privacy in mobile wireless sensor networks [PDF]
, 2013 Mobile wireless sensor networks (MWSN) is a subdomain of wireless sensor networks in which sensors and/or sinks are mobile. In this study, we propose a scheme for providing trajectory privacy of mobile sink nodes.
